Optical interface testing,

OLT, ONU equipment PON mouth receiving sensitivity test test steps: 1, the OLT and ONU equipment on electricity, after waiting for PON mouth working properly tested; 2, as shown in figure connection equipment instrument; 3, with FTTX optical power meter in R point test, optical attenuator, mediation test OLT PON port receiving sensitivity and ONU equipment PON receiving sensitivity. Expected results: when the OLT light module for 1000 base - PX10 maximum: - 24 DBM when OLT light module for 1000 base - PX20 maximum: - 27 DBM when the ONU light module for 1000 base - PX10 maximum: - 24 DBM when the ONU light module for 1000 base - PX20 maximum: - 24 dbmonu equipment PON mouth upward sent an average optical power test test steps: 1, the OLT and ONU equipment on electricity, after waiting for PON mouth working properly tested; 2, as shown in figure connection equipment instrument, must use special FTTX optical power meter; 3, with FTTX optical power meter in S point test, measure the uplink power value of 1310 - nm wavelength. Expected results: - 1. 0 to 4. 0 dbm
